Job summary

Quest Defense Systems & Solutions, Inc. seeks an embedded software engineer to design and maintain low‑level software for multicore processors and SoCs. You will implement processor init, inter‑core communication, and deterministic execution while integrating AV networking using TSN/ARINC standards.

The role demands DO‑178B/C processes, hardware bring‑up, and integration with FPGA/ASIC, with on‑site onboarding in Endicott, NY and periodic travel to the site. U.S. citizenship is required.

Qualifications

• Bachelor’s degree in Computer Engineering, Software Engineering, Electrical Engineering, Computer Science, or another relevant STEM discipline.
• 4+ years of embedded software or firmware development experience in aerospace, avionics, defense, or another safety‑or‑mission‑critical environment.
• Strong programming experience with embedded C and C++.
• Experience developing very low‑level, real‑time embedded software, such as BSPs, boot code, device drivers, processor initialization, or platform software.
• Hands‑on experience developing software for multicore processors or multicore SoCs.
• Experience with deterministic avionics networking or communications, including TSN, ARINC 664 Part 7 or AFDX, or related ARINC avionics standards
• Experience working within a DO-178B/C software development lifecycle.
• Experience with board bring‑up, hardware initialization, or hardware/software integration.
• Experience interfacing embedded software with FPGA, ASIC, or other custom hardware.
• Experience debugging embedded systems using hardware debugging or trace tools.
• U.S. citizenship.

Responsibilities

• Design, develop, and maintain low-level embedded software using C, C++, and Assembly.
• Develop software for multicore processors and SoCs, including processor initialization, inter-core communication, synchronization, shared-resource management, and deterministic execution.
• Develop and integrate deterministic avionics networking solutions using TSN, ARINC 664 Part 7/AFDX, PCIe, and related real-time communication technologies.
• Develop board support packages, boot code, device drivers, and other platform-level software.
• Support new hardware bring‑up, board initialization, and hardware/software integration.
• Integrate embedded software with FPGA, ASIC, and custom hardware components.
• Develop software in accordance with DO-178B/C processes and applicable safety‑critical requirements.
• Analyze and troubleshoot timing, latency, concurrency, and real‑time performance issues.
• Debug processor- and board-level software using hardware debuggers, trace tools, oscilloscopes, logic analyzers, and related laboratory equipment.
• Develop Python‑based tools to support debugging, testing, automation, and integration.
• Collaborate with software, hardware, FPGA, ASIC, systems, and verification engineers throughout the development lifecycle.
• Participate in software architecture, design reviews, testing, technical documentation, and continuous process improvement.
